SRAM’s latest video related to the American company’s eTap wireless groupset explains how the inspiration was the fastest wheeled vehicles on the planet, Formula 1 cars.
Often cycling follows where Formula 1 leads, the adoption of carbon fibre and wind tunnels for refining aerodynamics are just two examples.
Mirroring the the elite race cars SRAM decided to simplify the rider interaction with the gears to three simple actions.
Right paddle for up shifts and left paddle for down. To move the front mech press the paddles at the same time.
The result is a system which is said to make it nigh on impossible to mistake a down shift for an up shift. The paddle shifting system was not possible before with conventional mechanical or wired systems.
Batteries are still needed, but SRAM eTap is equipped with interchangeable battery backs that are light enough to attach the derailleurs.
The main concerns raised regarding the wireless set up is the potential interference, but SRAM claims the system’s wireless algorithm is encrypted more securely than any ATM.
After much anticipation eTap has definitely caused quite a stir with the UK SRAM distributor, Fisher Outdoor Leisure, confirming that its first batch of SRAM eTap systems have already been snapped up by its dealers.
